Sustainable living involves utilising resources to ensure their availability for future generations. When widely practised, it is an effective approach that can help restore the deteriorating environment. Sustainable products, made using biodegradable materials and minimal natural resources, facilitate the adoption of a sustainable lifestyle with ease. The occurrence of disease outbreaks and natural calamities indicates that a lifestyle shift is necessary to reverse the damage caused. Inevitably, social media has become an integral part of people’s lives, influencing their purchasing choices to some extent. This paper aims to examine this phenomenon in relation to sustainable products. It provides an overview of consumer awareness about sustainable products and investigates how social media influences consumer purchasing behaviour. The usage of products often leads individuals to incorporate sustainable practices into their daily lives. The study aims to determine if awareness and usage of sustainable products contribute to sustainable living. “Sustainable products” refer to goods and services that are designed, produced, and consumed in a way that minimises their impact on the environment, society, and economy, both in the short and long term. An online questionnaire was distributed to respondents residing in Chennai Urban, Tamil Nadu, to analyse this. The study sample consisted of 385 participants. The collected data was then analysed using simple linear regression to establish relationships. The study results demonstrated that respondents possess a good level of awareness about sustainable products, and social media does influence their purchasing behaviour to some extent. However, the results are positive but minimal when it comes to making a complete lifestyle shift. Although respondents are aware of sustainable products, achieving a comprehensive lifestyle change will likely require government intervention. It requires significant motivation for individuals to move beyond convenience and adopt a new lifestyle, as awareness alone often does not translate into behavioural change. Sustainability is a holistic approach that recognises the interconnectedness of environmental, social, and economic systems. It aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. Embracing sustainability is essential for creating a more just, resilient, and thriving world.
